running the ports at 1G on Trident-II is a no-no if there is egress
pressure on the 1G ports.  If the traffic bursts on the 1G port are
predominantly ingress, then that may not be a major issue.  Most
organisations will have traffic profiles which are substantially more
heavily loaded one way or the other, so this isn't as clear-cut as
"don't ever do this".  Monitoring egress drops is always a sensible
thing to do.

Also the trident chipset will only operate in cut-thru mode if all ports
on the device are configured to be the same speed, which will impact on
buffer utilisation.
